Anderson wrote, “I thoroughly enjoyed these past four years in Norman and am proud to have worn the crimson and cream. The bonds I formed with my teammates, coaches and friends are special to me and being selected captain this season has truly been an honor. With my degree already in hand and after much discussion with my family, I have chosen to set my sights on the NFL and focus on preparing for the 2019 NFL Draft. This was not an easy decision, but I believe I am ready for this next step.”

Anderson’s season was cut short when he suffered a season-ending knee injury against UCLA in Week 2. This was the second season-ending injury Anderson suffered as he sustained a broken leg in the second game of his freshman year too. Then in 2016, he suffered a neck injury before the season that cost him that entire fall.

But last season, Anderson burst onto the scene and rushed for 1,161 yards and 13 touchdowns. He also showed dual-threat ability, catching 17 passes for 281 yards and five touchdowns. In the College Football Playoff semifinal at the Rose Bowl, Anderson rushed for 201 yards and two touchdowns in the loss.
